WASHING MACHINE.

Application filed November 27, 1922; Serial No. 693,538.

This invention has reference to washing machines and particularly to thedomestic or household type machine.

The invention has forits principal object to combine in the oscillatortub type machine, the vacuum cup type machine; whereby the advantagesembodied in oscillating and vacuum cup machines are contained in onemachine.

This application discloses an improvement on the tub or containerforming the subject matter of the application filed by me October 12,1922, bearing Serial No. 594,019. In that caselthe cups, agitators, orpounders are more in the form of an attachment and the walls of thecontainer are constructed to receive the same. As herein disclosed, thevacuum cups are built in and, preferably located in the head walls ofthe container, producing a simple and inexpensive structure and yetobtaining substantially the same results as the structure referred to insaid mentioned application.

That the invention may be more fully understood, reference is had to theaccompanying drawings, forming a part of the present invention,illustrating a preferred embodiment of the invention, in which Figure 1is a vertical cross-section through a tub or container embodying myinvention;

' Figure 2 is a detail transverse section through the vacuum cups, asthe samewould appear on the line 2-2 Figure l, and

Figure 3 is a plan view in section looking up into the vacuum cups, asthe same would appear, if taken on the line 33 Figure 2.

Like characters of reference denote 'coralso the power unit, such as anelectric motor, er other means. A complete disclosure of these elementshave been shown in said pending application and may correspond theretoor be modified at the discretion of the manufacturer. I

The tub or container 1 is preferably intendedfto be mounted so that itmay be oscillated alternately in opposite directions. It is alsopreferably constructed of sheet metal and includes the side walls joinedby the curved preferably corrugated or ribbed rubbing wall 3 and thehead or top walls 4. The head walls are spaced and receive in such spacea central neck or inlet portion 5 of suitable contour, the opening 6 ofwhich is covered by a removable lid or cover, not

shown. The head walls 4 on either side of with their axes in upwardlyconverging relation and flangedly connected with said head or top wallsthrough the openings 8, somewhat in the manner shown in Figures 1 and 2.As shown, there are preferably three cups on each side of the neck 5,but by such showing it is not intended to limit the number of cups, as-Irealize such an arrangement is capable of" modification, and that anynumber of cups on either side of the inlet to the tub or container maybe pro vided' andstill be within the scope of the inventlon.

As in my pending application referred to, there is shown on the bottomof the tub or container a partition or obstruction 1-0,.

being a sheet preferably bent into the form of an inverted U to providea compartment; the walls having openings 11 therein for the circulationof water in the tub or container, and for the passage of water to adrain pipe, pokt) shown, when it is desired to drain the In operation,the vacuum cups will act on the water, as the tub is oscillated, firstin one direction and then in the opposite direction, and the waterforcing the air out of the cups into the water and through the fabricswill result in a cleansing of the fabrics. The oscillation of the tubwill move the clothing or fabrics toward and away rec lllfi acts to keepthe clothes or fabrics in agitation and to change the position thereofwithin the container or tub. Furthermore, the use of vacuum cups in anoscillatory tub or container have a suction effect on the clothing orfabrics as they are moved with the volume of water to thecups, and suchsuction will act to momentarily hold or re tard the fabrics as the waterfalls away due to the alternate action of the tub or container, and asthe water falls or moves away i What I claim is 15 A tub for Washingmachines having a spaced" downwardly and inwardly inclined head wallsadjacent its outer sides and an upwardly extending inlet portiondisposed in the space between the head walls, and 20 vacuum cupsconnected to the inclined head walls and projecting upwardly thereaboveand exteriorly thereof and having their axes inclined upwardly inconverging relation.

In witness whereof, I have hereunto affixed my handthis 25th day ofNovember, 1922.

ALPHEUS W. ALTORFER.
